Developments in Microbial Fuel Cell System for Electricity Generation

Over the last few years, world is facing problem of alternate energy source that has to be environmental friendly also. Microbes are present everywhere in environment that can oxidize different organic material and converts their chemical energy into electrical energy with the help of Microbial Fuel Cell (MFC) system through different catalytic reactions. Several cultures of microorganism like E.coli, Enterobacter aerogene, Geobacter sulfurreducens, Shewanella putrefaciens etc. have been tested for this and showed that energy can be obtained by them usng MFC system. Apart from the pure cultures waste water samples also showed to produce electrical energy with waste water treatment that improved the application of MFC. In this article several components and materials have been discussed that play key role for the performance of this system so that applications of MFC can be improved much and practical use of MFC can be a preferred option for the sustainable bioenergy source.
